. ELECTRIC-LIGHT CASING.

Specification of Letters Patent. Patented July-25, 1916;.

Application filed May a, 1916. Serial No. 96,130.

To all whom it may concern:

Be it known that I, WILLIAM- E. GUN- THER, a citizen of the United States, residing at Omaha,in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in 'Electric- Light Casings, of which the following is a" specification.

This invention relates to an electriclight' casing found to be of advantage in connection with graphophones, and has for its object to provide such a construction that the parts will be convenient'in use and ,will cupy a limited space near the rotatable table .or disk of a graphophone-for reflecting and :controlling the direction of the light, so thatthe operating parts may be adjusted with-.-.

out injury, and particularly as an aid'to an Operator to prevent injury to the record"- when applying the needle thereto. While useful for graphophones it may, of course,

be employed for other purposes. e

The. invention consists of the novelconstruction, combination and; arrangement of parts as described herein and claimedyand as illustrated in the accompanying drawing, I it being understood that changes in SlZB PI'O'.

portion and minor details may be made within the scope of the claims, without departing from the'spirit" of the invention 'or' sacrificing any of its advantages.

In the drawing, Figure lis a front view, partly in section, 'showing'tlie upper part of a graphophone, with the? device mounted, thereon. Fig. 2is' a view of the devicein longitudinal section. Fig. 3 is a frontview of the device. Fig. 4 a view similarto that shown in Fig. 3, a modified form of re flector being employed. Fig. 5 is a view in side elevation of the device. Fig. 6 is a side view of the same, the reflector being'similar to that shown in Fig. 4.

Referring now to the drawing fora more particular description, numeral -.7 indicates the case of 'a graphophone, and in order that light may be reflected to advantage as an aid to an operator when adjusting the parts of the graphophone which are above the horizontal partition 8, an upright housing 9 and hood or reflector 10 is employed for an electric light, the bulb of which is indicated at 11.

The housing consists, in part, of'a base or annular container 12, which maybe secured to the horizontal partition 8 by means of keepers 13, said partition;being-provided with an aperture 14 through which the electrical conductors 15, may pass, f r the light.

engage in the .upright wall of the base 12,

T Numeral 16 indicates a sleeve which'may said sleeve being provided near its lower end with an annular ridge or stop 17 and near its upper end wit-h an inwardly projecting, annular ledge 18 and a terminal, upa adapted to engage the ledge 18 and sleeve 19 so that it may be rotated for reflecting the light in a desired direction, the front side of said cylindrical reflector being provided with a rectangular opening .7) extending from near its flange 20 to its convergent top.

In' order that the seating of the reflector, upon'th'e ledge 18, may be secure,the base 12 is provided ,with a pair of catches or up- :wardly' projecting prongs 21, each preferably being formed with a transversely disposed bearing-plate 22 at its upper terminal for engaging the opposed sides of the-cylindrical hood, and an inwardly convergent 16, for maintaining the seating of the sleeve uponthe base.

At 23 is indicated a cone shaped reflector,

provided with a collar 10' having an in Wardly projecting, annular flange 20 adapted to bear on the ledge 18 and to engage the flange 1910f the sleeve 16, and this reflector which, in operation, concentrates the rays of light effectively, may be'substituted for the reflector, 10, whenever desired, theplates 22 bearing upon the opposed sides of the collar 10. 4 i

part 0, intermediate its ends, for engaging theinwardly convergent 'wall d of the sleeve It will be noted that, in the drawing, the

constructionillustrated by Figs. 2, 3 and'5, is the same as the construction shown in Figs); and 6, with the exception that the reflectors are of diflerent forms, and this is a desirable feature so that the reflectors may be changed whenever required.

Byuse of the device, the operating parts of a graphophone may be visible for the purposes mentioned, the reflectors may be changed conveniently, and by swinging the 1 resilient prongs outwardly the sleeve may be readily removed or replaced, this being an advantage since operation may be facili- -.tated and threaded parts may be dispensed lindrical part provided with an inwardly projecting, annular flange, a base member provided with an upright, annular wall, an upright sleeve circumscribed by andhaving an annular stop member adapted to bear upon the upright annular Wall of said base member, said sleeve being provided nearits upper end with an inwardly projecting, annular ledge to provide a seat for the annular, inwardly projecting flange of the reflector, and having a terminal, annular flange projecting above said ledge adapted to be circumscribed by the flange of said reflector.

2. An electric light housing, comprising, in combination with a reflector having a cylindrical part provided with an inwardly projecting, annular flange, a base member provided with an upright, annular wall and with a pair ofupright prongs, an upright sleeve supported by the base and provided near its upper end with an inwardly projecting annular ledge to provide a seat for the annular, inwardly projecting flange of the reflector, and having a terminal, annular flange projecting above said ledge for engagement with the flange of the reflector, the prongs of the base member projecting above the annular ledge of the sleeve for engaging the cylindrical part of said reflector.
